- W2938990511 abstract "INTRODUCTION:Coronary artery heart disease and rheumatic heart disease are among the most common causes of morbidity and mortality in India. These two diseases are the most common causes of cardiac failure. Patients with these diseases should have regular follow-up with doctors.Impaired pulmonary function is common in cardiac patients. Respiratory muscle wasting has been well documented in Rheumatic Heart Disease patients. But Pulmonary Function Test is the least common test that is undergone by the patients. This current study is aimed to assess the Pulmonary Function of cardiac patients with coronary artery heart disease and rheumatic heart disease who have recovered from cardiac failure.AIMS AND OBJECTIVES:1. To study the Pulmonary Function Test patterns in patients with coronary artery heart disease and Rheumatic Heart Disease who have revived from Cardiac Failure.2. To diagnose any underlying undiagnosed respiratory problem coexisting with cardiac failure.MATERIALS AND METHODS:This study is a observational study conducted in Department of Medicine, Tirunelveli Medical College Hospital. Seventy five patients admitted in TVMCH from MAY 2014 to MAY 2015 will participate in the study. The volunteer patients who met the inclusion criteria, signed a consent form after they got a clear explanation of the spirometry evaluation procedures.Inclusion Criteria:1. Adult patients with Rheumatic Heart Disease (Male and Female).2. Coronary artery heart disease patients less than 60 years of age (Male and Female).Exclusion Criteria:1. Pediatric patients less than 12 years of age and Adult patients more than 60 years of age.2. Rheumatic Heart disease patients with known respiratory disease (COPD, Bronchial Asthma, Pulmonary Tuberculosis)3. CAHD patients with known respiratory disease (COPD, Bronchial Asthma, Pulmonary Tuberculosis) Morbid and sick patients.4. Severe Left Ventricular Dysfunction patients as per ECHO report.Data Collection:1. Detailed medical history and physical examination is done.2. Basic Laboratory investigations such as complete blood count, RFT and Urine analysis done.3. ECG,4. X-Ray Chest PA view,5. Echocardiogram,6. Spirometry test.SPIROMETER:The spirometry is performed using a device called a spirometer, which comes in several different varieties. Most spirometers display the following graphs, called spirograms:1.A volume-time curve, showing volume (liters) along the Y-axis and time (seconds) along the X-axis2.A flow-volume loop, which graphically depicts the rate of airflow on the Y-axis and the total volume inspired or expired on the X-axisPROCEDURE:The basic forced volume vital capacity (FVC) test varies slighty depending on the equipment used.Generally, the patient is asked to take the deepest breath they can, and then exhale into the sensors hard as possible, for as long as possible, preferably at least 6 seconds. It is sometimes directly followed by a rapid inhalation (inspiration), in particular when assessing possible upper airway obstruction. Sometimes, the test will be preceded by a period of quiet breathing in and out from the sensor (tidal volume) or the rapid breath in (forced inspiratory part) will come before the forced exhalation.During the test, soft nose clips may be used to prevent air escaping through the nose. Filter mouthpieces may be used to prevent the spread of microorganisms.DISCUSSION:This study “study of pulmonary function tests in cardiac patients” is an observational study done on 75 patients revived from cardiac failure.The parameters studied were forced expiratory volume in first second (FEV1), forced vital capacity (FVC) and ratio of FEV1/FEV. Among the studied patients, 52% had normal pattern of pulmonary function test, 32% had restrictive pattern and 16% had obstructive pattern.Both males and females had similar type of distribution of pulmonary function test pattern. Compared to cardiac failure patients with coronary artery disease, patients with rheumatic heart disease had lower proportion of patients with normal pulmonary function test pattern. The prevalence of restrictive pattern of pulmonary function test was more in those with rheumatic heart disease than those with coronary artery heart disease.The prevalence of obstructive pattern was more in patients with left ventricular ejection fraction of less than 50%CONCLUSION:The presence of impaired pulmonary function tests in cardiac failure patients has been already demonstrated in various studies. This study concludes that more than half of the cardiac failure patients had normal pulmonary function pattern. In those who had abnormal pulmonary function pattern, incidence of restrictive pattern was more than that of obstrictive pattern. The prevalence of restrictive pattern of pulmonary function test was more in patients with rheumatic heart disease than coronary artery disease patients. As LV ejection fraction of patients with cardiac failure decreased there is a higher incidence of obstructive pattern of pulmonary function test." @default.
